To all whom it may conoern Be it known that l., 'Cnlnngns l?. Qrrxor, a citizen ot' the United States, residing' at Ocononiowoc, county of livanliesha, State oi Wisconsin, have invented a certain. new and useful improvement in insulated lil-ail- Joints, and declare the following to he a tall, clear, and exact description of the saine, such as Will enable others skilled in the art to which it pertains to malte and use the same, reference being' had to the accompanying drawings,- which forni a part of this specification.

My invention relates to joints rior railway rails, i'iarticnlarly those in which the two rail ends are to he electrically .insnlateifl from each other and it has for its object to iinprove the construction of the same. Y

The various features of novelty which characterize my invention will be hereinafter pointed ont with particnlarity in the claim, hut for a full understanding' oit my invention and of its object and advantages reference is to be had to the 'following detailed description taken in connection with ti, e accompanying drawinnr wherein:

Figure 1 is a side elevation of a joint arranged in accordance with a preferred einbodinnent of iny invention; Jig. Q .is a section on line 2 2 oil Fig. l; 3 is plan view on a smallerseaie showing; the hase plate; Fig. fi is a View similar to Fig'. 3 showing' the insulatingA niemher between the hase plate and the rail; and Fig. 5 is anend view of the insulating ineniher.

Referring' to the drawing, and A rep` resent two rail ends.

B, B are two tish plates cach ha ving' a ven tical ineinher b fitting' between the head and the hase of each of the rails and a laterally projecting flange hearingl upon the iop ot' the base of the rail and extending laterally beyond the base. The lower faces of the flanges b, o', lie above the plane of the nndersurface of the rail hase.

C, C indicate layers of insulating nn'iterial arranged between the fish plates and the rail so as to prevent metallic Contact, between the same.

D0, D0 are bolts pa ne lhronghlhe fish plates and the webs ot vthe rails so as to tie the parts rigidly together. yThe helts are preferably insulated 'troni the fish plates as by means ol bushings n, c.

D is a i'lat hase plate equal in length to the ish plates and preferably of such a width that its side edges lie directly beneath the outer edges ot the tlanges ZJ.

E is a slab oit insulai g material preteraoly of the saine shape as the hase plate, lying between the base plate and the bottoni oi the rail so as to insulate the hase plate from the rail. ln order te avoid leaving space beneath the flanges oi the i'ish plates and thereby decreasing the rigidity of the support, l thicken the member E along` the sides thereof so that when the parts are assenihlecl the flanges of the isn plates are borne directly from the hase plate through the insulating` incniher. The flanges of the ish plates, the insulating nien'lher E, and the hase plate are all tied together into one solid structure by means of bolts F, l".

there the insulating ineinher E is inode ot' a hoard or sheet of liber Vprefer to eil'ect the thickening; at the edges by means oi" liber strips e, e, which are secured to the upper surface of the niain ineniher, preferably hy ineans oi rivets e. These rivets neecl not he employed, but they are convenient since it is unnecessary to insulate the flanges of the `ish plates from the hase plate and it is therefore innnatinial whether or nos rivets nialie metallic contact with tish plates and the base pate.

it is sometimes desirahle to provide 1in auxiliary stitlening directly at the jointy hetween the two rails and where sneh the case a downwardly depending chord B i'nay he formed at the middle of each ot the lish plates. The sides oi' the base plate and of the insulating lneinber are then ent an. .y at. ohiliosite sides as at D and se' velg: so as to provide for the i; un ol the downwardly depeinling ln this case, also, the strips ot insnla ing material do not run throughout. Vthe entire length of the main insulating member, but only short pieces are employed at each corner.

it will now he seen that l have prof'ifled an insulated ioint which is extremely simple in emistrncton and in which absolute ri lity is obtained since there is a solid hearin; between the several parts at erery point.

lll-living now fully described my invent inn, what l claim as new and oesire to secure i Leiters Patent is:

in an insulated rail joint, the con'ihination ot two adjacent rail ends, lish plates arranged between the heads and the hases of -jecting laterally beneath the flanges on the the shape of the base plate, said Slab being thickened at each of its corners so to tit snugly between the ianges of the lish plates and the base platej bolts passing through the sh plates and the Webs of the rails, and l bolts for tying the llanges of the fish plates, l the insulating slab and the base plate into one solid structure.

In testimony whereof, l, sign this specifitish plates, Said base plate hai/ing portions cation in the presence of t'wo Witnesses. removed from opposite sides thereof to ie- CHARLES F QUINCY ceive the downwardly projecting chords on l the sh plates, a slab ot' insulatingmaterial Witnesses: arranged between said base plate and the C.
